| | | | | | | | in the trunk (r6483). Since the expression 3 * (n0 + 1) is used later, this makes the code more readable; but as oldn0 is a multiple of 3, both tests are equivalent (and equivalent to oldn0 <= 3*n0). git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/branches/2.4@6500 280ebfd0-de03-0410-8827-d642c229c3f4

Check underflow of arctan(Inf) and arctan(1) with reduced exponent range. atan.c: fixed bug when x is very near but differs from 1 atan.c: expand exponent range when computing arctan(Inf) and arctan(+-1).
